To all whom 'it may concern." y

Be it knownthat I, HARRY L. IDE, citizen of the United States, residing at Springfield, in the county'of Sangamon-and State of Illinois, haveinvented ya certain new and useful Improvement in Engines, of which the following is a full, clear, concise, and lexact de- Scriptlon, reference being had :to the accompanying drawings, forming apart of this specification.

` My invention relates to engines, and has several advantages and objectsin view, as

` will appear by the following description of u ing bolts servingto clampthe flanges and the preferred embodiment of my invention shown in the accompanying drawing, in whichc i Y Figure lis a view `in elevation, Inainly in section, of a portionof an engine constructed in accordance with ,the invention. Fig. 2 is a view of parts of themechanism shown in Fig. l, taken in a direction at right angles to that'in which 'Figrl is taken. Fig. 3 is a detail view of a part ofthe` mechanism shown in Figs. l and 2.

Like parts are indicated by similar characters of reference throughout the different figures. l

In accordance with my invention, the crank shaft of the engineis formed in two separable sections a o, respectively provided with enlargements cV al integrally formed therewith and laterally proj ectinof therefrom. These enlargements are desirably in the form'of circular flanges that are set vface to face when the shaft sections are to be assem- V bled. A governing element` supporte, desirably in the form of a wheel, is designed `for interposition between the? flanges c (Zand is` desirably provided [with insetV `recesses, as Indicated most clearly In Fig; 1, for receiving the flanges o d, said recesses-having av` common bottom portionV f, which is the vpart of the governing element support that I in-` y Clamping bolts g are passed through the flangesand also terpose between the flanges.

preferably through the; bottom portion if of the governing element sufpport,these 'clampthe governing element vsupport firmlyto earch other..` An elementof the engine governor is illustrated at tfandis ofa kind whichis ernor illustrated. VThis governing elementli i is mounted at z' upon the support e and hasV connection at 7c with a valve-controlling ele- `ment shown in the `present embodiment of l theinvention in the form of a swinging eccentric Z mounted to rotate upon a pivotal lshaft m screwed into one of the flanges, cl. Thefeccentric Z for purpose of having oper- Qative interconnection with the governing element, is provided with a bar n forming a part of the eccentric structure and having.

connection, as stated, with the governing element at la and provided with a counter- This eccentric is made balancing weight o. in Vtwo pieces in orderthat it may readily be placed over the shaft. These pieces are `bolted together.

The engine indicated is of the side crank type, the'crank p being indicated upon th'e end of the shaft section o, the crank being provided with a crank pin q and other adjuncts that need not be mentioned. A bearing r is Vindicated between the crank p and y the governing ,mechanism Many advantages of the novel construction illustrated and herein claimed will be readily apparentto those skilled in the art.

With the usual construction hitherto employed, the shaft is made entirely of one piece', even where it is employed for driving dynamos. As a consequence, it has been customary `to make the entire shafts to special dimensionsto suit the requirements of the generator. By means of the construction herein set forth, the section of the shaft (L) carrying `the crank, may be of standard construction, `and the companion section (a) `which is Ito carry the armature of the genferator, may be constructed to suit the generator `to which it is to be adapted. The shaft ofVthis` construction, in combination with `a governing element support held between the flanges of the sections of the shaft, avoids the necessity of using a split governor pulley on aside crank engine, such pulleys having hitherto been split for thepurpose of enabling them to be readily handled, without removing the armature `from the shaft. By -means "of my invention, the two shaft sections need', merely be uncoupled and separated, in order to removethe governing elementV support. Furthermore, by my improved arrangement of the governing element `support in combination with the sectional shaft; said support or pulley is not likely to run out of true with respect to the shaft', which hitherto has happened because of loose or improper fit of the pulley hub upon the shaft.

It will be seen that the governor pulley in my present construction becomes so rigidly fixed with respect to the shaft when the bolts g' are properly tightened, as to render the pulley absolutely rigid with respect to the shaft sections. It will also be seen that the governing element and the governor pulley may, with the greatest facility, be erected or dismantled. By mounting the governor eccentric upon the pin m attached to a shaft flange, great accuracy is insured in the location and maintenance of the relative position of the engine crank and eccentric.

It will be apparent that there are great advantages which result from mounting the eccentric upon an enlargement integrally formed with the shaft. The force imparted by an eccentric when. driving a valve and its connections, acts in a line passing approximately through the center of the eccentric. Consequently, the nearer the pivotal point of support for the eccentric is brought to the center of the eccentric, the shorter will be ,the lever arm upon which it acts and the less will be the moment tending to disturb the position of the eccentric and the more stable will be the eccentric for a given weight and power of the governor. It will be seen that for a given degree of stability for the eccentric, a lighter governor may be used when the pivotal point of support for the eccentric is broughtcloser to the center of the eccentric. It will further be seen that the shorter the lever arm from the pivotal point of support to the center of the eccentric, the less will be the side-play of the eccentric in a direction lengthwise of the engine shaft for a given degree of ease of fit in the pivotal bearing of the eccentric.

The desired close approximation of the pivotal support for the eccentric and the center of the eccentric is readily obtained by making the mounting for the eccentric an integral enlargement of the shaft.

All of the advantages above pointed out are securable when the pivotal or mounting point of the eccentric is provided upon an enlargement integrally formed with the engine shaft, as must be apparent.

There are other advantages in my improved construction which need not be herein particularly set forth, and as it is obvious that changes may readily be made in the preferred embodiment of my invention herein illustrated, without departing from the spirit of the invention, I do not wish to be limited to the precise construction shown, but,

I-Iaving thus described my invention, I claim as new and desire to secure by Letters Patent the following l.'
